To all whom it may concern: ki

kBe it known that I, 'WILLIAM H. ANDER, a citizen of the ,UnitedStates,-and a resident of Long Branch, in thel county of Monmouth andState of New Jersey, 'have invented a new and Improved Concrete- Mold,of which the following is a full, clear, and exact description.

My invention relates to concrete molds and it has for its object toprovide one hav-k ing a bottom member which may be conV` venientlyrotated and lowered so that a detachable end member will rest on theground, the mold being provided with side members which have clamps forengaging the detachableend member, and means by which the side membersare' moved laterally relatively to the bottom member.Y f

Additional objects of the invent-ion will appear in thefollowing'complete `specification, in which the preferred form of theinvention is disclosed.

In the drawings similar,y characters of ref* erence indicatecorresponding parts in all the views, in which Figure 1 is a sideelevation of` theinvention.; Fig. 2 is a fragmentary sectional view onthe line 2-2 of Fig. A1, with the body member disposed in a yverticalposition; Fig. 3 is a front elevation of Fig. 2; Fig.4` is an end viewshowing kthe body membery in an inverted position; Fig. 5 isa sectionaleleva` tion showing the body member in a vertical position; Fig. 6 is afragmentary sectional View showing the means by which the clampingmembers are connected with the rods, by which they are operated; andFig. 7 is a perspective view showing one ofthe bearing members.

` By referringk to the drawings it will be seen that a frame isprovided, consisting of the side members 5, which are connected by atransverse member 6, which is right angular in cross section, thistransverse member 6 being riveted to the side members 5 at 7. Supportingwheels 8 are journaled inthe `sides 5 of the frame. The top of the sidemembers 5 have bearing surfaces 9, on which the bearings 10 of thebearing members 11 are adapted to rest, these bearing members 11 havingguide ,members 12, which are' disposed in the guideways 13, secured tothe side members 5. At the lower terminals of the guide members 12vthere are depending ears 14, which are adapted to be engaged-.by

ALEX- the cams 15, which side members 5. w n Secured to a rock shaft 17,which is jour-` naled in bearings 18 in t-he side members 5, there arecams 19, these cams 19 being adapted to engage thecams 15 for movingthem, and raising the guide members 12.y Stops 20 are secured to theside members 5 for limitingk the movement., of the kcams 19.` There issecured to the shaft 17, at'the outer Specification of Letters Patent. YPatented Dec. 17, 179127.y i

are pivoted'atll to the l l l side of one of the side members 5, a lever'21,' by which the rockshaft 17 maybe conveniently-moved, as maybedesired.

Journaledv in the bearings 10 there isa body member 22 rhaving flanges23, ywhich are engaged by the flanges 24Qon the end member 25y whichforms part of the bodyYK member, the flanges 23 andl24 being secured v ftogether by bolts 26. A study 27 is disposed in an opening v28 in thebody member 22,

this stud 27 being` held inplace .by a' vset* screw 29. Mounted torotate on. the studf27 there isa wheel 30 having cam grooves 31".'Fulcrumed at 32 to the bottom `of the body member 22 there are levers33, one'jset of terminals 34 of the said levers 33' being dis.- posed inthe cam grooves 31, the other set of terminals 35 of the levers 33 beingarticuf lated to laterally disposed tie members v36,

these tie members 36 having upwardly disposed terminals 37.

Two side members 38 are provided, these side members resting normally onthe body member 22, the body member 22 .having lateral `projections 39,which are adapted to support the sidemembers 38 when theyl are movedoutwardly. Straps 40 are secured to the outer sides of the sidelmembers'38,and in these straps 40 A there are disposed tiedmembers 41,the tie members 41 having straps 42 in which are disposed the terminals37 of the tie vmembers 36.y

Blocks 43 are secured to the sides of the side members 38, so that whenthe tie mem* 'bers 36 are drawninwardly, they will carry i with them theside members without anyv lost motion. The clamping kmembers `41 haveflanges 44, vwhich are normally disposed in recesses 45, in theremovable endmember 46 of the mold. Springs v47 are provided one foreach of the 4clamping members 41, the

springs connecting the clamping members with one set of straps 40, sothat the clamp#y ing members 41 will be held yieldingly in a" fpredetermined position relativelyto theside members 38, the end member25 of the mold having lateral projections 48, each with a slot 49, theclamping members 41 being disposed in these slots 49. The head members50 are provided with threaded orifices in which the terminals 51 of theclamping members 41 are disposed, nuts 52 being provided for engagingthe threaded terminals 51 to lock the head members 50 in position.

Articulated to the head members 50 one at each side, there are links 53,these links 53 being connected by a transverse member 54 to abut againstthe terminals 51 of the clamping members for moving the said terminalsinwardly. rlhe link members 53 have terminals 55, which rest against therear of the lateral projections 48 of the end member 25. To theterminals 55 of the links 58 there are articulated brackets 56, thebrackets 56 at each side of the machine being riveted to rods 57, therods 57 being articulated to wrist pins 58, secured to the wheel 30.rThe wheel 30 is provided with a crank 59, by which it may beconveniently turned.

Projecting` from one of the bearings 10 there is a journal 6G, to whicha head member 61 is articulated on an axis which is vertical when thebody member is in horizontal or normal position. Secured to this headmember 61 thereV is an arm 62, with a hook 63, the hook 6B being adaptedto engage and rest in the recess 64, in the bracket 65, which isintegral with one of the side members 5. A lever 66 is secured to thehead member 61, the aXis of the lever being at right angles to the axisotl the pivot 67, which connects the head member 61 with the journal 60.A transverse member 6 is provided with a threaded head 68, in whichmeshes a screw 69, the screw 69 being provided to engage the body member22 at 70, and serve as a stop for the body member.

In using the invention the side members 38 and the removable end member46 are disposed in position with the flanges 44 engaging the recesses 45in the removable end member, and withthe clamping members 41 drawnvrearwardly and toward the center line of the machine to lock the sideand removable end members, the mold formed by the body member the sidemembers and the end members, is filled with concrete. rI`he device isthen moved into a position where the operator desires to remove theconcrete which is disposed in the mold. The operator moves the lever 66toward the center line of the machine, which disengages the hook 63 fromthe recess 64, in the bracket, and he then raises the lever 66 to rotatethe mold to the position shown in F ig. 5 of the drawings. The lever 21is then raised slowly, the movement o f the cams 19 permitting the cams15 to move downwardly and with them the bearing members 12. In this waythe mold is moved toward the ground until the removable end member 46rests on the ground. The operator then rotates the wheel 30 by means ofthe crank 59, so that the rods 57 are moved outwardly, and the arms 34of the levers 38 are moved inwardly. This movement of the wheel 30 willmove the links 53 into the position shown in Fig. 2 of the drawingswhich will draw the clamping members 41 outwardly, and with them therear of the side members 38, andalso free their flanges 44 from therecesses 45. At the same time the movement of thellevers 83 will movethe tie members 36 outwardly. As the clamping members 41 and the tiemembers 36 are moved outwardly they will carry with them the sidemembers 38, and will permit the operator to raise the mold by a downwardmovement of the lever 21, the concrete being deposited on the removableend member 46, and being disengaged from the body member 22 of the mold,when it is raised. As the sidevmembers 38 have been moved away from theconcrete by the rotation of the wheel 30, only one surface of the moldis in contact with the concrete when the body member is raised. However,if desired, the device may be moved rearwardly from the concrete so thatthe concrete will no longer be in contact with any member of the mold,when the body member is raised by the downward movement of the member21. After the body member has been raised as has been described thelever 66 is operated to bring the body member to a horizontal position,as it is moved outwardly, so that the hooks 63 will be again disposed inthe bracket 65. Another end member 46 is then provided, and is disposedin position, when by a rotary movement of the crank 59 the ianges 46 onthe clamping members 41 will be locked in the recesses 45, in the newend member 46, and, at the same time, the side members 38 will be drawninwardly, and will be locked with the end member 86, to permit of there-illi'ng of the mold. It will be understood that when the clampingmembers 41 are moved to lock their tlanges 44 in the recesses 45 in thenew end member 46, the springs 47 will draw the side members 38 intoplace.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:
